Or for that matter, high end ARM chips :)
In terms of power efficiency you'll need to wait until Apple stops monopolizing TSMC's N5 node.
Apple almost singlehandedly invented the ARM64 ISA, and bankrolled the leading-edge TSMC process, so it's probably okay for them to have the best SoC for a while as long as others have a fair chance of catching up soon.
IMO, Nvidia is comparing themselves to embedded vendors. For general compute, I'd like vendors to keep up with the Fedoras, sids, and Tumbleweeds of the world, at the very least. Not asking for arch, btw :)
Hopefully Nvidia's server ambitions with Grace will see them take on general compute.
Something higher end would be fantastic too, but this feels like a walk before we get to run kind of situation.
